Explanation / Answer

For SSN:

Code:

import java.util.*;
import java.util.regex.*;
class Validations {
public static void main(String args[]) {
   Scanner keyboard = new Scanner(System.in);
   System.out.println("Enter SSN:999-99-9999:");
   String SSN=keyboard.nextLine();
   String regex = "^(?!000|666)[0-8][0-9]{2}-(?!00)[0-9]{2}-(?!0000)[0-9]{4}$";
Pattern pattern = Pattern.compile(regex);
   Matcher matcher = pattern.matcher(SSN);
   if(matcher.matches())
   System.out.println("Valid SSN");
   else
   System.out.println("Invalid SSN");
   }
   }

Similarly

for Phone number:

Refular expression is:^\(?(\d{3})\)?[- ]?(\d{3})[- ]?(\d{4})$";

for ISBN:

^[0-9X]{10}$";

import java.util.regex.*;
class Validations {
public static void main(String args[]) {
   Scanner keyboard = new Scanner(System.in);
   System.out.println("Enter SSN:999-99-9999:, or Enter Phone number :(999) 999-9999,or an ISBN:99999999X: ");
   String input=keyboard.nextLine();
   String regexSSN = "^(?!000|666)[0-8][0-9]{2}-(?!00)[0-9]{2}-(?!0000)[0-9]{4}$";
   String regexPHNE ="^\(?(\d{3})\)?[- ]?(\d{3})[- ]?(\d{4})$";
   String regexISBN="^[0-9X]{10}$";
   Pattern patternSSN = Pattern.compile(regexSSN);
   Pattern patternPHNE = Pattern.compile(regexPHNE);
   Pattern patternISBN = Pattern.compile(regexISBN);
   Matcher matcherssn = patternSSN.matcher(input);
   Matcher matcherphne = patternPHNE.matcher(input);
   Matcher matcherISBN = patternISBN.matcher(input);
       if(matcherssn.matches()){
   System.out.println("Valid SSN");
}else if(matcherphne.matches()){
   System.out.println("Valid Phone Number");
}
else if(matcherISBN.matches()){
   System.out.println("Valid ISBN");
}
else{
System.out.println("Invalid format");
}
   }
   }

sample output:

123-45-6789

Valid SSN
